Collection of indirect excitons in a diamond-shaped electrostatic trap
A. A. High, A. K. Thomas, G. Grosso +7
We report on the principle and realization of a new trap for excitons -- the diamond electrostatic trap -- which uses a single electrode to create a confining potential for exciton…
Localization-Delocalization Transition of Indirect Excitons in Lateral Electrostatic Lattices
M. Remeika, J. C. Graves, A. T. Hammack +5
We study transport of indirect excitons in GaAs/AlGaAs coupled quantum wells in linear lattices created by laterally modulated gate voltage. The localization-delocalization transit…
Coherence Length of Cold Exciton Gases in Coupled Quantum Wells
Sen Yang, A. T. Hammack, M. M. Fogler +2
A Mach-Zehnder interferometer with spatial and spectral resolution was used to probe spontaneous coherence in cold exciton gases, which are implemented experimentally in the ring o…
Trapping of Cold Excitons with Laser Light
A. T. Hammack, M. Griswold, L. V. Butov +3
Optical trapping and manipulation of neutral particles has led to a variety of experiments from stretching DNA-molecules to trapping and cooling of neutral atoms. An exciting recen…
Charge transport and phase transition in exciton rings
L. V. Butov, L. S. Levitov, A. V. Mintsev +3
The macroscopic exciton rings observed in the photoluminescence (PL) patterns of excitons in coupled quantum wells (CQWs) are explained by a series of experiments and a theory base…
